Small Duct High VelocityCentral Heating & A/C System

SpacePak At-A-Glance

Cool, Evenly Distributed Air

The basic difference between SpacePak and other air conditioning systems
is the way SpacePak actively circulates air within the room and throughout
the structure's entire living/working space. Circulating the air more
effectively is what makes a home with SpacePak central air so uniformly
comfortable: no cold or warm spots, no drafts, and up to 30% more humidity
removed.

Conventional central air systems merely drop cold air in at the ceiling;
the distribution of cool air is haphazard, leading to over-cooling in some
spots or drafts in others.

Window air conditioner units or mini-splits require noisy fans within the
living space to blow the air around, and there is no overall circulation of
the home's air.

Small, Flexible Tubing Instead of Sheet Metal Ductwork

A central heating or cooling system designed to actively circulate air can use smaller
ducts than conventional systems; 2 inch mini duct insulated supply tubing keeps
the air moving consistently—like pouring water from a pitcher. This smaller duct
allows SpacePak to use flexible tubing to distribute the air instead of bulky
sheet metal ductwork.

This tubing is seamless, so it doesn't waste energy through leaks like sheet metal.
And it's flexible, so passages have no corners to accumulate dust, pollen, or mold.
The tubing's narrow diameter allows it to be placed in the spaces behind walls,
floors, and ceilings: it can be installed with virtually no disruption to livable space,
nor to interior architectural features.

Central Air Built Around the Space You Have... or Want

SpacePak can be installed into either new construction or an existing structure.
Either way, the simplicity of SpacePak's sized-to-fit tubular ducts requires just
a fraction of the installation time and cost associated with having sheet metal ductwork
fabricated and installed. No other company has more experience designing and building
central air systems with the flexibility to fit into virtually any building. SpacePak
is ideal for:

historic buildings

buildings without existing ductwork

buildings that utilize radiant heat systems

open floor plans

log homes/cabins

brownstones or row houses

lofts

additions

modular homes

The Basics of a SpacePak Central Air System

While every installation is configured specially to the individual home's
unique requirements, fundamentally the SpacePak system consists of the
following components as labeled in the diagram below. Each one is briefly
described below.

Outlets

Sound Attenuators

Kwik Connects

Flexible Ducts

Plenum

Fan Coil Unit

Return Air Duct

Return Air Box/PurePak Air Cleaner (optional)

Outlets: How the conditioned air enters the living space.
These 5" diameter outlets (the size of a music CD; much smaller
than conventional register grilles) can be placed in the ceiling, wall, or floor.

Sound Attenuators: Short lengths of flexible, baffled tubing.
These tubes greatly reduce the audible sounds produced in the air movement process.

Flexible Supply Tubing: These flexible, narrow, tubular ducts
enable SpacePak to bring central air throughout the house within the normal space
between walls, ceilings, or floors: no extensive renovation work. The number of ducts
would be based on the size of the fan coil unit.

Plenum: Carries air to the different ducts which distribute it
throughout the house. The plenum fits within the attic, basement, or crawl space
where the fan coil unit is installed.

Fan Coil Unit: The fan distributes air through the plenum; the coils cool
(or heat and cool) the air, depending on individual needs and system configuration.
Connects to external condenser for cooling; SpacePak is compatible with most
condenser brands.

Return Duct: The central heating or cooling system contains a blower
that gets its air supply through this duct. The air from a room will move towards the
lower pressure of the return duct. The duct also contains the properties of sound
attenuation and is insulated.

Return Air Box: This is the sheet metal box that mounts directly
to the return air grill. This allows the mating of the return duct to the grill.

PurePak Air Cleaner (optional): A patented design that replaces the
standard return air box. While 4–6" pleated filters are not effective at removing
contaminants smaller than three microns (such as bacteria, auto exhaust,
cooking smoke, dust, or paint pigments), PurePak captures contaminants as small
as 0.3 microns with 97% effectiveness.
